What the packet contains

Sections in FEMA checklist order. Each heading names the review item its tables support; whether the item is satisfied is decided by the plan and its reviewers. Full tables are in the downloads above.

Supports B1-a Hazards

14 of the 18 National Risk Index hazards apply here; omission evidence is shown only where NRI rates a hazard "Not Applicable", no federal declaration names it and Storm Events has no record of it since 1996.

Highest expected annual loss (NRI, modeled): Inland Flooding, Earthquake and Tornado.

Also check locally (not covered by NRI): dam failure (incl. upstream dams), levee failure, flash flood as its own subtype, ice jams, debris flows, erosion (riverine and coastal), land subsidence and sinkholes and expansive soils.

Check your state hazard mitigation plan's hazard list for this county; explain any hazard you drop.

Supports B1-b Location

  • Avalanche, Coastal Flooding, Earthquake, Hurricane, Landslide, Tornado, Tsunami, Volcanic Activity and Wildfire: Census tract rating counts from the National Risk Index tract table (see B1-f). Tract maps and place names are not in this packet.
  • Cold Wave, Drought, Hail, Heat Wave, Ice Storm, Lightning, Strong Wind and Winter Weather: Affects the whole planning area; national data do not distinguish locations within the county. Confirm locally.
  • Inland Flooding: The FEMA Flood Insurance Rate Map (FIRM) is the required location source for flooding. See the FEMA Flood Map Service Center (https://msc.fema.gov) for this county.

Supports B1-c Extent

Storm Events records for 14 of 20 hazard groups, with the scale, observed range and worst recorded event for each; the others say local data required.

  • Hail: 4.25 in hail, 2012-01-22
  • Thunderstorm Wind: 83 kt (96 mph), measurement type not recorded, Thunderstorm Wind, 1990-05-12
  • Tornado: F3 tornado, 1983-05-14, 5 mi path length (records before 1996 may include the whole path; rating and listing come from the county where the tornado began), 100 yd wide, $2,500,000 property; crops not recorded (1983 dollars), 2 direct injuries

Supports B1-d Previous occurrences

25 federal declaration rows for this area (20 counted incidents), each with type, dates and county Public Assistance dollars.

New since the last plan (approved 2026-09-21): none.

6 statewide declarations listed separately.

Hazards with no recorded events are stated as such (5 of 18).

Storm Events history: 772 records (notable ones in the PDF, all of them in the Excel file).

Supports B1-e Probability

FEMA annualized frequency (modeled) for each hazard, with a descriptor from a scale defined in the packet.

  • Highly likely: Hail, Lightning and Strong Wind
  • Likely: Drought, Heat Wave, Ice Storm, Inland Flooding, Landslide, Tornado and Winter Weather
  • Possible: Cold Wave, Hurricane and Wildfire

Historical frequency by intensity band (tornado, hail, wind): 9 bands from Storm Events.

Supports B1-f Variation across the planning area

Range of census tract risk scores within the area for 18 hazards (24 tracts; rated tracts only).

8 member jurisdictions: plan clock, repeat-flood count, Public Assistance dollars and event records naming the place (starter, confirm locally).

Supports B2-a, B2-b Assets and impacts

County-level starter. The plan must describe impacts for each participant and its own assets.

Storm Events damage since 2026-09-21: none reported in county-coded records (0 records); none reported reported for the zone (0 zone records). Data through 2026-06-30; nominal dollars.

Checklist of what to gather locally: Critical facilities and lifelines per hazard; A problem statement per participant per hazard; Changes in development in hazard-prone areas since the last approval, or a statement of none (E1-a); Future assets.

Supports B2-a Context
